Officials said the raid was a part of an investigation into accusations of physical and emotional abuse at the school. It's unclear when the allegations were first made, but police said their investigation began in January.

Puntin, Meadow, Swift and Lopez-Lucas face charges of assault and battery on a disabled person. Lopez-Lucas is also charged with assault and battery with a dangerous weapon, while Davis is charged with intimidation and obstruction of justice.

"The investigators who carried out the execution of the search warrant Saturday night at the Eagleton School should be commended for their professionalism and sensitivity to the students' privacy," Berkshire County District Attorney David Capeless said in a statement. "The operation was conducted with minimum presence, and reports back to me indicated that normal operations at the school were not disrupted and the students were unaware of the law."

All five suspects were released on personal recognizance and are due in Great Barrington District Court Monday. It was not immediately clear if the suspects had attorneys.
